Essentia bumper antenna issue

My 2017 Chevrolet Essentia with a gasoline engine has a weird issue. The error memory has an error stored related to the bumper antenna. Now the unlocking/locking acts up, and I can't start the engine without the key in the ignition. Anyone seen this before?

Summary of the thread

The problem was suspected to be related to the antenna cable or connections, possibly due to loose or corroded connections. The suggested solution was to inspect the cable and connections for damage or corrosion, and ultimately, the issue was resolved by a professional repair, confirming a defective connection as the cause.

Sounds like a real headache. Bumper antenna issues can be sneaky. If it's not unlocking/locking properly and affecting the engine start, it's more than just a radio problem. It's like a domino effect. Have you checked the antenna cable and connections? Sometimes a loose or corroded connection can cause all sorts of electrical gremlins.

Where exactly should I be looking for this cable and connections? Any tips on what to look for specifically? I'm not super experienced with car electrics.

Think of it like tracing the veins of a leaf back to the stem. Start at the bumper where the antenna is located and follow the cable. Usually, it runs along the frame. Look for any obvious damage to the cable itself – cuts, frays, or kinks. Then, check the connections at each end. Are they snug? Any corrosion? A little bit of green crud can cause big problems. Given the symptoms, and that it could be the cable or plug connection of the component, it may be best to take it to a shop.

Thanks for the advice. Ended up taking it to a shop, and you were right – it was a defective connection. Cost me 95€ to fix. Appreciate the help!
